Abstract

We have developed a novel encapsulation method for flexible organic light-emitting diodes (OLEDs) using poly(dimethylsiloxane) (PDMS). The new method, which uses polycarbonate film, silicon dioxide, and PDMS, was found to enhance the lifetime of OLEDs in air. Optical measurements of the preservation of calcium films encapsulated with PDMS showed that the water and oxygen permeation rates of the PDMS encapsulation were reduced from a level of 0.57 gm-2 d-1 (bare substrate) to 1 × 10-7 gm-2 d-1. These results indicate that the PDMS barrier coatings have a good potential for flexible OLED applications.
